145, you subtract the total number with how many you sold
523-378=145
Answer:
E
Step-by-step explanation:
I just think so. Maybe it's right
Answer:
Step-by-step explanation:
Using the proportion test
Null hypothesis: p <= 0.22
Alternative hypothesis: p > 0.22
Using the formula
z score = p - P /√ (P(1-P)/n)
Where p is 74/200= 0.37, P = 0.22, n = 200.
0.37-0.22 / √(0.22(1-0.22)/200)
0.15 / √(0.22(0.78)/200)
0.15 / √(0.1716/200)
0.15/ √0.000858
0.15 / 0.02929
= 5.1212
To help arrive at a conclusion, we have to find the p value, using a p value calculator at the 0.05 level of significant, the p value is less than 0.00001... Thus we would reject the null as there is sufficient statistical evidence to prove that the proportion is higher than that reported by the polling organization.
<span>draw out a triangle and then create three boxes inside by drawing a T. In each of the boxes you've created you need to put one of the letters from the equation. The equation you currently have is F= m*a. To rearrange this equation put the m and the a into the bottom boxes and the F above. Because there is a vertical line between the m and the a, this means you times them. If there is a horizonal line between two letters you divide them. So to find a, you must divide F by m. </span>
